ABSTRACT (9F THE DISCLOSURE A bank of pile yarns is shogged weftwise in one direction in a stepwise manner to loop the pile yarns beneath each of a plurality of successive picks and over successive groups of warp yarns while forming loops therefrom over the groups of warp yarns. The direction of shogging is reversed and the operation is repeated to complete a shogging cycle. During the latter part of the shogging cycle or subsequent to each cycle, the loops extending over alternate groups of warp yarns are severed to form short U-shaped cut pile tufts having legs of substantially equal length and to form abnormally long U-shaped cut pile tufts having legs of substantially equal length by retracting pile yarn portions from beneath certain picks.

This application is a division of my copending application Ser. No. 520,256, filed Jan. 12, 1966, and relates to a new and novel method of making out pile fabrics and more especially to making a woven shaggy cut pile fabric having abnormally long cut pile tufts.

Woven cut pile fabrics, including fabrics having cut pile tufts of two or more different lengths looped beneath corresponding weft yarns, are well known. To my knowledge, however, where U-shaped cut pile tufts have been provided on a pile fabric heretofore, the legs of abnormally long U-shaped tufts have not been of substantially equal length and arranged in alternation with short U- shaped cut pile tufts also having legs of substantially equal length.

It is therefore an object of this invention to provide a method of making a woven cut pile fabric, which fabric comprises a ground or base of U-shaped short and abnormally long cut pile tufts looped beneath corresponding weft yarns and wherein the legs of each short tuft are of substantially equal length, and the legs of each long tuft are of substantially equal length, with the short and long tufts being positioned in warpwise and weftwise rows and the short and long tufts being arranged in alternation in at least the warpwise r-ows.

According to a preferred commercially practical method of the present invention, a loop pile fabric may be woven as a single-shot fabric with certain loops being cut and resultant cut pile tufts being materially increased in length by applying a robbing technique thereto. This robbing technique enables the formation of abnormally long cut pile tufts utilizing pile wires whose loop forming portions are of substantially conventional height, so that no serious problems of pile wire rigidity or of maintaining the pile wires erect are presented. In the absence of the robbing technique of this invention, however, abnormally high loop forming portions would be required on the pile wires in order to form pile tufts of the length proposed according to the instant invention. Since pile wires are necessarily quite thin, such abnormally high loop forming portions would be extremely diflicult if not impossible to maintain erect and rigid under the tension of pile yarns looped thereover. Further, if a way could be devised to use pile wires having abnormally high loop forming portions, the fabrics resulting there- States Patent C "ice from would not have the legs of the respective U-shaped cut pile tufts of equal length as in the instant invention. Also, since the fabric of this invention may be woven as a single-shot fabric, this permits a substantially high rate of production as compared to the rate of production at which a comparable cut pile fabric may be produced when woven as a two-shot or multi-shot fabric.

More specifically, this invention is directed to a novel method of forming a cut pile fabric wherein warp and weft yarns are interwoven while a bank of pile yarns is shogged weftwise in one direction in a stepwise manner such as to loop the pile yarns beneath each of a plurality of successive picks and over successive groups of warp yarns while forming loops therefrom over the groups of warp yarns. The direction of shogging the bank of pile yarns then is reversed while the pile yarns are again looped beneath each of a plurality of additional successive picks and successively over the same groups of warp yarns to complete a shogging cycle. During the latter part of or subsequent to each successive shogging cycle, the loops extending over alternate groups of warp yarns are severed to form short U-shaped cut pile tufts having legs of substantially equal length and also to form corresponding free end pile yarn portions which are retracted from beneath certain picks to form therefrom abnormally long U-shaped cut pile tufts having legs of substantially equal length. 1

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which FIGURE 1 is a schematic plan view of a preferred embodiment of the woven cut pile fabric of the present invention showing progressive stages in the production thereof;

FIGURE 5 is a schematic perspective view clearly illustrating the alternating arrangement of the short and abnormally long U-shaped cut pile tufts in warpwise and weftwise rows;

FIGURES 8 and 9 are fragmentary vertical sectional views through the fabric looking in the weftwise direction and taken substantially along the respective lines 8-8 and 9-9 in FIGURE 2A.

Referring more specifically to the drawings, and especially to FIGURES l, 2 and 2A, a preferred embodiment of the fabric of the present invention comprises a base or ground fabric formed of interwoven warp and weft yarns. Thewarp yarns include closely spaced groups of warp yarns, the particular groups shown in FIGURE 1 being indicated atW1-W12. Warp yarn groups W1-W8 are shown in FIGURES 2 and 2A. The particular weft yarns shown in FIGURE 1 are indicated at L1-L15. Pile yarns P1P13 are also shown in FIGURE 1, all or any number of which may constitute a bank of pile yarns. Although each group of warp yarns W1-W12 includes a plurality of warp yarns, and each weft yarn L1L15 in FIGURE 1 may include a plurality of strands therein, the warp and weft yarns are shown in FIGURE 1 in the form ofrespective narrow strips to present a clearer representation of the pile yarns and the cut pile tufts formed therefrom. However, the sections of the fabric shown in FIGURES 2, 2A,6 and 7 clearly illustrate the warp yarns in each group and also illustrate the several weft strands of each weft yarn.

In both FIGURES 1 and 2 the fabric is shown as it is being woven and as'the pile loops are being formed thereon and then cut and then raised to rob or retract portions of the legs of abnormally long U-shaped cut pile tufts from beneath certain of the weft yarns. The fabric of this invention may be woven on a suitably modified loom of a type such as is disclosed in Mobergs US. Patent No. 2,860,664 and which is characterized by the fact that pile yarns are shogged laterally to and fro over warpwise extending pile formers resting upon a ground fabric being woven and wherein the pile yarns are dipped downwardly into the shed following each lateral shogging motion of the pile yarns so weft yarns are positioned over the pile yarns prior to corresponding beat-ups of the Weft yarns against the fell.

As best shown in the upper portion of FIGURE 1, starting at the weft yarn L11 and reading upwardly in FIGURE 1, it will be noted that the pile yarns Pl-P13 are shogged in one weftwise direction (to the right in this instance) in a stepwise manner to loop each pile yarn beneath each of a plurality of successive picks, such as picks or weft yarns L11, L12, L13, and over successive groups of Warp yarns while forming loops therefrom over the corresponding groups of warp yarns, after which the direction of shogging of the pile yarns is reversed to again loop the pile yarns beneath each of a plurality of additional successive picks, such as the picks L14, L15, and successively over the same groups of warp yarns while again forming loops over the corresponding groups of warp yarns to complete a shogging cycle.

More specifically, it will be noted that, taking a single pile yarn, such as pile yarn P3, for example, pile yarn F3 is looped beneath weft yarn L11 between the warp yarn groups W1, W2, and then is shogged over warp yarn group W2 and over a corresponding low pile former or Wire, not shown in FIGURE 1 (see pile wires 20 in FIG- URES 2 and 4), to form a raised relatively short loop from the pile yarn P3 over Warp yarn group W2. Thereafter, pile yarn P3 is looped beneath weft yarn L12 and is then shogged to the right in FIGURE 1 over warp yarn group W3 and over a corresponding relatively higher pile former or wire, not shown in FIGURE 1 (see pile wires 21 in FIGURES 2 and 4), to form another loop therefrom. Thereafter, pile yarn P3 is looped beneath weft yarn L13 and the direction in which the pile yarn is being shogged then is reversed; i.e., shogging of the pile yarns commences from right to left in FIGURE 1. Thus, it can be seen that pile yarn P3 is then looped again over warp yarn group W3 and over a corresponding relatively high pile wire to form a loop therefrom. Thereafter, weft yarn L14 is inserted through the fabric and pile yarn P3 is looped beneath weft yarn L14. Pile yarn P3 is then shogged again from right to left in FIG- URE 1 over warp yarn group W2 and the corresponding low pile wire to again form a relatively short raised loop 4 i above warp group W2, after which pile yarn P3 looped beneath weft yarn L15 to complete a shogging cycle of pile yarn P3. All pile yarns Pl-P13 may be manipulated in unison over the corresponding bank of pile wires 20, 21 in the manner described with respect to pile yarn P3.

Portions of a pair of pile wires especially constructed for weaving and forming cut pile tufts according to the present invention are shown in FIGURE 4 wherein a short-pile-tuft-former or pile wire is indicated at 20 and a long-pile-tuft-former or pile wire is broadly designated at 21. As shown in FIGURES 2 and 3, pile wires 20, 21

are arranged in alternation weftwise of the fabric being woven and extend warpwise over respective groups of warp yarns. It will be observed in FIGURES 3 and 4 that pile wires 20, 21 include respective loop forming and supporting sections 22, 23, the loop forming section 22 preferably being of substantially lesser height than loop forming section 23.

Both the pile wires, or at least the portions thereof illustrated in FIGURE 4, rest upon the ground fabric 10 during the weaving of thefabric and the relative positions of the pile wires 20, 21 are substantially as illustrated in FIGURES 3 and 4 wherein it will be observed that the forward or left-hand portion of each pile wire 20 terminates a substantial distance short of the front end of each pile wire 21 and has an upwardly and forwardly angularly disposed cutting blade 24 thereon which is located rearwardly of successive stages, steps or shoulders 25, 26 formed on eachlong-tuft-forming pile wire 21. Thus, since the fabric moves from right to left relative to the pile wires 20, 21 in FIGURE 4, the loops, which are formed by a lateral shogging of the pile yarns in the manner heretofore described, are formed over the loop forming sections 22, 23 of the pile wires 20, 21, and the low or short loops formed over loop forming section 22 of pile wire 20 are severed by cutting blade 24 before at least the leading corresponding pile yarn sections or free end portions engage the first step 25 of the adjacent high tuft pile wire 21. As best shown in FIGURE 3, it will be noted that the legs of the high loops formed over pile forming section 23 of pile wire 21 are successively engaged and momentarily restrained by the trailing edge of step 25, but as the fabric advances relative to the pile wire ,21, this permits the trailing portion of the corresponding high pile loop to move into juxtaposition with the leading portion thereof, and thereafter, both the leading and trailing legs of the corresponding long pile loop move upwardly onto step 25. In so doing, referring again to FIGURE 1 at weft yarns L8, L9, L10, as well as FIGURE 3, it will be observed that the free end portions of corresponding abnormally long cut pile tufts being formed are retracted from beneath the portions of corresponding weft yarns positioned most closely adjacent the group of yarns above which the corresponding pile yarns were cut. More particularly, referring again to the pile yarn P3 in the central portion of FIGURE 1, it will be noted that, as the fabric moves downwardly in this figure relative to corresponding pile wires therebeneath, the pile wire 21 positioned above warp yarn group W3 will have its shoulder 25 (FIGURE 4) engaging the.

portion of the high tuft A3 extending over warp yarn group W3 adjacent opposite sides of weft yarn L9, and in so doing, it will retract the leading portion of the corresponding abnormally long cut pile tuft A3 fromv beneath weft yarn L8. Also, the shoulder 25 on the corresponding pile wire 21 will also place the trailing free end portion of the pile yarn tuft A3 being formed of pile yarn P3 and extending under weft yarn L10 under abnormal tension momentarily. Thereupon, the cutting blade 24 (FIGURE 4) on the adjacentpile wire 20 then positioned above warp yarn group W2 will sever the pile yarn P3 so that the trailing leg of the corresponding cut pile tuft A3 in FIGURE 1 will be at least partially retracted from beneath weft yarn L10.

Since the fabric advances relatively slowly relative to the pile wires, there may be a relaxing of the free end portions of the tuft A3 looped beneath weft yarn L9, during which the free end portions further retract from beneath the corresponding weft yarns L8, L10. Thereupon, both legs of the corresponding relatively long cut pile tuft A3 are engaged and raised above the corresponding warp yarn group W3 of FIGURE 1 by the second step on the corresponding pile wire 21 to completely retract the free end portions of the legs of the corresponding U-shaped tuft A3 being formed from beneath weft yarns L8, L10.

Now, it will be observed in FIGURE 4, that the front free end portion of pile wire 21 has a very high projection 27 thereon which is provided with an upwardly and forwardly inclined upper edge surface 30 thereon which extends upwardly from step 26. Thus, as the latter tuft A3, and any other abnormally long cut pile tufts aligned weftwise thereof, are advanced relative to pile wires 21, the two legs of each such abnormally long U-shaped cut pile tuft whose central portions are then looped beneath weft yarn L9, are then fully raised or distended by engagement thereof with the inclined surface 30 on the front end projections 27 of the corresponding pile wires 21. The abnormally long cut pile tufts formed from respective pile yarns Pl-P12 are respectively designated at A1A12 and the short pile tufts formed from the respective pile yarns P2-P13 are respectively designated at B2-B13, where applicable.

It is important to note that, by shogging and interlacing the pile yarns in the manner shown in the upper portions of FIGURES 1 and 2, for example, then cutting the same and employing the robbing technique of retracting the legs of the abnormally long cut pile tufts A1-A12 from beneath certain of the weft yarns in the manner heretofore described, so that the central portions of the tufts remain looped beneath respective weft yarns, the legs of each short U-shaped tuft are of substantially equal length and the legs of each long U-shaped tuft are of substantially equal length. In commercial practice, it has been noted that occasionally one of the legs of a long cut pile tuft may be undesirably retracted more than the other; i.e., the loop of the tuft may shift beneath a corresponding weft yarn, so one of the legs thereof may project above the face of the pile, which condition may be rectified in subsequent processing. As particularly illustrated in the lower portion of FIGURE 1 and in FIGURES 2A, 3, 5, 8 and 9, it will be noted that a warpwise row of tufts is formed between each adjacent pair of groups of warp yarns with the short and long U-shaped tufts being arranged in alternation in the warpwise rows. The warpwise rows of short and long tufts arranged in alternation also form weftwise rows of short and long U-shaped tufts arranged in alternation and wherein the tufts in the weftwise rows are looped beneath alternate weft yarns, such as the weft yarns L1, L3, L5, etc. (FIGURE 1), with the intervening weft yarns, such as L2, L4, L6, etc. being free or devoid of any cut pile tufts being looped therebeneath. It is important to note that the fabric, as shown in the upper portion of FIGURE 1 and in FIGURE 2, may be woven as a one-shot or single-shot fabric, but that in severing the short loop pile tufts, which are located at alternate groups of warp yarns, the fabric is converted into a two-shot fabric as shown in the lower portion of FIGURE 1 and in FIGURE 2A. As is well known, a one-shot pile fabric is so constructed that a pile loop is formed of each pile yarn between each adjacent pair of weft yarns or picks. On the other hand, a two-shot fabric is characterized in that two picks or shots of weft yarns are inserted for every weftwise row of loop or cut pile tufts.

In order that the U-shaped pile tufts need not be made from unduly large, and thus expensive, pile yarns and may still be spaced a suitable distance apart from each other weftwise of the fabric so that the distance between adjacent tuft-s weftwise of the fabric may conform substantially to the distance between adjacent legs of the tufts warpwise of the fabric, while aiding in locking the tufts in the ground fabric 10, it will be observed in FIG- URES 2 and 6-9 that each Warp yarn group Wl-W12 may include five warp yarns and each weft yarn may include four weft strands. In FIGURES 6 and 7, only the warp yarn groups W1-W5 are shown. However, it is to be understood that each warp yarn group W1W12 may be similarly arranged. It will be observed in FIG- URES 2, 6 and 7 that each group of warp yarns includes three chain warp yarns C1, C2, C3 and two stuffer warp yarns S. The stulfer warp yarns, which are substantially straight throughout the length of the fabric when the fabric is resting upon a flat surface, preferably are located between the corresponding chain warp yarns C1, C2, C3 in each warp yarn group. As shown in FIG- URES 8 and 9, each weft yarn may include two upper strands 35, 36 positioned in side-by-side relation to each other and which extend above stuffer warp yarns S. Each weft yarn may also include two lower strands 37, 38 which extend beneath the stuffer warp yarns S throughout the width of the fabric in side-by-side relation to each other so the stuffer yarns S extend in a substantially straight line throughout the length of the fabric as opposed to extending over and under the successive weft yarns. The chain warp yarns C1, C2, C3 loop over and under and tightly engage successive weft yarns as shown in FIGURES 8 and 9.

In this connection, it will be noted that chain warp yarn C2 is positioned between the chain warp yarns C1, C3 (FIGURES 6 and 7) and that wherever a chain warp yarn C2 passes beneath a pair of weft strands 37, 38 (FIGURES 8 and 9), the chain warp yarns C1, C3 pass over the corresponding upper pair of weft strands 35, 36. It is also apparent by referring to FIGURES 8 and 9 that chain warp yarns C1, C3 extend over alternate weft yarns and beneath intervening weft yarns between said alternate weft yarns while the chain warp yarns C2 extend beneath the alternate weft yarns and over the intervening weft yarns, thus providing a heavy tightly woven ground fabric which firmly locks the tufts therein.

Although the fabric of the present invention may be formed from pile yarns all of the same color, very pleasing aesthetic effects may be produced by carefully choosing pile yarns of different colors and by a careful pattern arrangement of the different colors of pile yarns with respect to each other. By utilizing pile yarns of more than two different colors or shades as best shown in FIGURE 1, for example, the sinuous manner in which the pile yarns are interwoven with the ground fabric 10, due to multiple-step shogging of the pile yarns over two or more successive groups of ground warp yarns in the manner heretofore described, presents a multi-colored random appearance to the fabric, although the three or more colors of pile yarns are arranged in a predetermined pattern sequence. As shown in FIGURE 1, three different colors of pile yarns are used, wherein every other pile yarn (termed as a first pile yarn) or alternate pile yarns, such as P2, P4, P6, etc., may be white or of a first color while alternately spaced second pile yarns, such as pile yarns P3, P7, P11, etc., between alternately spaced pairs of the first pile yarns, may be of a second color or shade, such as blue, and the remaining or third pile yarns P5, P9, etc., between intervening pairs of the first pile yarns, may be of a third color, such as green.

Since the short cut pile tufts of the instant fabric are considerably shorter than the long cut pile tufts, they are substantially shielded and hidden by the long tufts so that all the adjacent legs of tufts of different colors in adjacent warpwise and weftwise rows are randomly interspersed with respect to each other. For example, it will 7 be observed that the legs of the tufts which extend over the weft yarn L4 in FIGURE 1, collectively provide a randomly variegated appearance to the corresponding portion of the fabric, which appearance is present over the entire pile surface of the fabric. More specifically, reading from left to right in FIGURE 1, the legs of the abnormal ly long cut pile tufts which overlie weft yarn L4 may be green, white, blue, white, green, white, blue, white, green, white, blue and white in that order. It is apparent therefore, that the arrangement of the three different colors of pile yarns in a predetermined pattern sequence substantially as shown in FIGURE 1 presents a very pleasing,

multi-colored random appearance to the fabric. In this connection, it is apparent that similar variegated elfects may be obtained by utilizing two or more pile yarns of different shades or colors throughout the fabric or in selected areas instead of single pile yarns P1P13.

It is thus seen that I have provided a novel woven cut pile fabric in which U-shaped cut pile tufts of short and abnormally long lengths are provided and wherein the legs of each short tuft are of substantially equal length and the legs of each long tuft are of Substantially equal length with short and long tufts being positioned in warpwise and weftwise rows and arranged in alternation in both the warpwise and weftwise rows. The short tufts may be very short; i.e., the short tufts may extend only a short distance from the ground fabric, with tuft lengths of about one-fourth inch having been found to be practical. Further, the legs of the abnormally long cut pile tufts may be up to or greater than six times longer than the length of the legs of the short pile tufts when measured from the upper surface of the ground fabric, but in any event, the legs of the long pile tufts should preferably extend more than one inch from the ground fabric, with lengths of one and onehalf inches to one and three-fourths inches having been found to present very desirable shaggy fabrics. The preferred ratio of the length of the legs of the short pile tufts to the legs of the long pile tufts is about one to six with the long pile tufts extending more than one inch from the ground fabric.

In the drawings and specification there has been set forth a preferred embodiment of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
